FRUIT-DRIER.

SPECIFICATION forming part of Letters Patent No. 276,202, dated April 24, 1883.

Application filed January 31, 1883. (No model.) 7

To all whom it may concern Be it known that I, EDWARD .MGGAUGHEY TURNER, a citizen of the United States, residing at Knoxville, in the. county of Knox and State of Tennessee, have invented a new and useful Fruit-Drier, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to fruit-driers for baking, drying, and evaporating fruits and vegetables of all kinds; and it consistsincertain I view on the line 3 yin Fig.2.

Fig. 5 is a horizontal sectional view on theline c o in Fig. 2. Fig. 6 is a detail view of the radiator detached, and Fig. 7 is a detail view of one of the drying-trays.

The same letters refer to the same parts in all the figures.

A in the drawings designates the outer case of myimproved fruit-drier,wh ich may be constructed of sheet metal, 1umber,or other suitable material, and of any shape desired, either round, rectangular, or elliptical in cross-section or otherwise. In the drawings a casing rectangular in cross-section has been shown.

At the corners of this are four vertical flues,

B B, extending from the top to some distance below the bottom of the casing, so as to form legs or supports upon which the casing rests, as will be seen in the drawings. I (l is a suitably-constructed furnace, locate near the bottom and extending from the front to therearside of the casing. Said furnace has at its front end afeed-door, D, and draft-openings E, and at its rear end it is provided with draft-openings F, which maybe covered by a slide, G.

His a vertical flue, located atth'e rear end of and outside the casing A, and connected at its lower end with the furnace by an elbow, I,

,above which a damper, J, is located.

Fig. 2 is a vertical sectional view on the line a; m in Fig. 1. Fig. 3 is a vertical transverse sectional Fig. 4; is a horizontal sectional view on the line a z in Fig. 2..

The furnace G is provided with a centrallylocated collar, K, projecting upwardly Within the casing, and to which the radiator L is connected. Said radiator consists of a suitablycoiled or otherwise constructed pipe, the inner end of which has a vertical pipe, M, by which it is connected with the collar K. Its outer end is connected by a pipe, N, with the draftflue above the damper J. In the said draftflue, above the pipe N, is another damper, 0.

It will be seen that by closing the latter and.

opening the damper J the products of combustion are compelled to pass through the collar K, radiator L, and into the draft-flue, thus thoroughly heating the interior of the drier. Draft may then be had from both ends of the furnace. By opening both dampers and closing the rear draft, the tendency of the draft will be direct through the elbow I and into the draft-flue. By manipulating the dampers the force of the draft may be regulated in the usual manner.

At the sides of the furnace, in the lower end of the casing, are arranged two slanting deflectors, P P, connecting the front and rear sides of the casing, and extending nearly to the bottom, so that cold air may enter and be thrown by the deflectors P P over againstthe furnace. From the upper edges of the deflectors P bottom platcs,Q Q, extend slantingly upward to the sides of the outer casin g. Itis between the inner edges of these bottom plates and deflectors that the heat from the furnace enters the drier-casing.

The rear side of the drier-casing is provided at some distance above the furnace with a ledge or flange, R, which serves, in conjunction with side cleats, S S, to support a dished false bottom, T, having a central longitudinal slot, U, over which is placed an inverted box or trough, V, the sides of which are provided with openings The heated air,'in order to enter the body of the drier-casing, must pass through the slot U and openings W, which serve to diffuse it thoroughly and evenly throughout the drier.

X is the inner case of my improved drier, which is made of sheet metal or other suitable material, conical or pyramidal in shape, its slanting sides bein g connected to the inner corners of the tines B near the upper ends of the latter, and to the sides of the outer casing at or about the point at which the slanting bottom plates,-Q, are connected to the said casing. Between the inner and outer casing are thus formed foul-air spaces or chambers Y, which are connected with the dues B by means of openings Z in the sides of the latter. The moisture-laden air will thus pass from the body of the drier-case over the upper edges ofthe inner casing or lining into the foul-air spaces Y, from thence through the openings Z and into the tines B, down through the latter, and. out through openings A in their lower ends.

The drier is provided with a top plate, B from which a flue, 0 extends upwardly, as shown. The said fine is provided with a damper, D and with a cap .or cowl, E

The front side of the drier-casing A is provided,just above the furnace,with a slide-door,. F for admitting cold air into the drier in case I the latter should become overheated. The: front side of the drier-case is provided \Vitb doors G having double backs H whichare= open at the top and bottom, as shown at 1 The lower edges of the door-openingsarez provided with inwardly-projecting ledgesor flanges J having perforations K enabling; the hot air to pass between the front and back. sides of the doors, thus preventing the parts; of the drier near the doors from becoming: cooled by contact with the outer air.

L. L are cleats secured to theinner sides-of the dues B, for supporting-the drying-trays The latter, which are denoted by M may be madeof wire-netting,with suitably constructed sheet-metal frames. The said trays are also' provided with one or more openings, N other than those in the netting, and which may be surrounded with collars These openings are for the purpose of enabling the heated air to pass through and between the trays and be-- come thoroughly diffused in the drier.

The operation ofthis invention will be readily understood from the foregoing description, taken in connection with the drawings-hereto annexed. The drying-trays are inserted and removedthroughthe doors G Cold air enters at .thebottom of the drier, becomes heated S by contactwith the furnace and withthe radiator, and ascends into the body of the drier-- case, where, owing to the peculiar construe-- tion herein described, it becomes thoroughly and evenly diffused, thus drying the fruit evenly throughout. The 'vapors pass over the upper edgesof theinner easing into the foulso as to form legs or supports independent of the body ofthe casing, by which the body of the casing is raised above the floor, as set forth.

2. In afruit-drier, the combination, with the casing, of the furnace extending from the front to thereariend of thelatter, and having draft-openings at its front and rear ends, the draft-flue connected'to the rear end of said furnace, a radiator having one end connected to the topof said furnace," coiled within the drier-casing, and having its other end connectedto the draft-flue, and dampers located in the latter between the furnace and radiator and above the latter, as set forth.

3. The combination of the drier-casing, the furnace, arranged in the lower part'of and extending from the front to the rear end of the same, the slanting deflectors, arranged adjoiningthe sides of the. furnace andconnected to the front and. rearsends of the casing, and the bottom: plates, connected to the upper edges of the deflectors. and slanting upwardly and outwardly to the-sides .otlthe casing, as herein described fo-r the purpose set forth.

4. The combination, withthe drier-casing having slanting deflectors-and bottom plates,

.and the furnace and. radiator, of the dished ,longitudinally slotted false bottomv supported 6. Inafru-it-drier; the combination of the outer case,-.the vertical corner flues having openings near-their upper and lower ends, the

slanting deflectors and bottom plates, and the inner casinghaving; conically or pyramidally slanting sides extendingfrom'near the top of the outer case, where they are connected to the inner corners of the flues,-toabout the point where the slantingbottom platesjoin the sides of the outer casing, substantially asand for thepurposer-set forth.

7. vInafruit-drier, the-casing having door- .open-ingssprovidedt atitheir lower/edges with inwardly-projecting. perforated ledges, in combinationwiththe/doorshavin-gfalse or double backs-open at the top and bottom, substantially as and for=the purpose set forth.
